Logo designing

Tonight, I spent some time in polishing 3 logo designs for a friend. The requirements were the initials T & S, colours red & black, & a diamond. From my initial sketches, I chose 3 ideas that I wanted to expand on in Adobe Illustrator. As you can see, I did make use of the gradient function to create a jewel effect of the diamond and an illuminating effect in the letters. I hope that my friend likes what I have created so far.
